Since its founding in 1990, BCY Fibers has cemented its reputation as one of the most trusted names in archery string materials, serving bowhunters, competitive shooters, bowmakers and string builders worldwide. What started as a focused entry into the specialized world of bowstring fibers has grown into an industry standard for safety, consistency, durability and performance.
At its core, BCY’s mission has always been to understand not just the mechanics of archery, but the precise needs of those who live it. The company’s leadership and product development teams are deeply involved in the sport, drawing on feedback from both amateur and professional archers. This insight drives continuous improvement of their materials and ensures BCY products not only meet but exceed industry expectations.
Material Innovation and Bowstring Excellence
BCY specializes in high-performance fiber materials used to make bowstrings, crossbow strings, serving threads and related accessories. The company primarily uses advanced synthetic fibers like Dyneema® (a high-modulus polyethylene) and Vectran, chosen for their superior strength and creep resistance—creep being the slow, permanent elongation of string material that can affect bow performance over time.
One of BCY’s flagship materials is 452Xtra, a patented construction composed of a blend of Dyneema® and Vectran fibers. It builds on the legacy of earlier strands like 452X by offering improved abrasion resistance and stability without sacrificing strength or performance. Available in a full spectrum of colors and spool sizes, 452Xtra is suited for everything from compound bows to traditional recurve setups.
Other standout materials include:
- X-99®, which combines high-quality SK99 Dyneema with Vectran for low fuzziness and excellent abrasion resistance, making it popular for both compound and recurve applications.
- Mercury and Mercury 2, pure SK99 Dyneema options that deliver very low creep and high strength ideal for both compound bows and crossbows.
- 8125® and DynaFLIGHT 97®, classic Dyneema fibers that provide a balance of speed, durability and reliability across multiple archery disciplines.
- B55, a 100% polyester string material favored by many traditional and recurve archers for its durability and low stretch behavior similar to classic materials like Dacron.
Serving Material and Accessories
Beyond string cores, BCY offers a comprehensive lineup of serving materials and accessories that protect and enhance bowstring performance. Serving—a protective wrap around key high-wear areas of a string—is crucial for durability and consistency. BCY’s serving products like Powergrip, Halo™ Serving, Majic and 2X End Serving provide a range of options for different shooting styles and performance needs.
The company also stocks archery accessories such as loop rope, nock point and peep tying thread, waxes formulated for bowstring care, bow fishing lines, and instructional DVDs for string building—illustrating BCY’s commitment to supporting the entire archery community, whether hobbyist or professional.
A Trusted Resource for Archers Worldwide
What truly sets BCY apart is its dedication to technical understanding and customer service. The company doesn’t just sell fibers—BCY collaborates with the archery community to evolve its offerings, ensuring archers have access to materials that enhance accuracy, stability and longevity. Their products are specified as original equipment by major bow manufacturers and remain popular with hunters and competition archers alike.
Whether you’re crafting a custom bowstring, repairing old gear, or seeking premium performance materials, BCY Fibers provides a deep catalog backed by decades of industry expertise.
